Abstract

The invention discloses a detection device capable of accurately positioning chips, which includes a base, a conveyor belt, and a screening mechanism for detecting and screening chips. The conveyor belt is arranged on the base, and the There are support rod 1, support rod 2, guide rod 1, support plate 1, support plate 2, guide rod 2 and mounting plate vertically, guide rod 2 is vertically arranged with the conveyor belt, guide rod 2 is above the conveyor belt, The mounting plate is above the conveyor belt and close to the conveying end of the conveyor belt. When the chip is conveyed on the conveyor belt, the motor 2 can drive the sliding frame to move along the mounting frame 1, and the sensor 2 can locate the position of the probe , so as to facilitate the detection of the chip. The sensor one is also a distance sensor. When the motor one drives the sliding frame to move along the X direction, the sensor positions the pair of detection pins, which is conducive to the detection of the chip.

Description

technical field [0001] The invention relates to the technical field of chip screening, in particular to a detection device capable of accurately positioning chips. Background technique [0002] In the prior art, the chips are packaged in bulk, that is, the finished chips are laser-cut together into small-sized chips required by the design, and removed from the blue film by chip suction equipment to form a single small chip. After sucking into a single chip, individual batches need to test the single chip one by one due to the process or experiment. At this time, it is necessary to manually use tweezers to arrange the chips uniformly in the positive or negative direction in the specified area. Moreover, in the prior art, the retesting work for the finished chip is manually placed on the metal plate, and QT2 is used to test the reverse voltage value VR and the reverse leakage current value IR. The efficiency of manual detection is low, which is not conducive to chip inspection...
